Last Updated on 13/03/2021

Experiment name:
Study on compare between single jersey single truck (conventional) and single jersey four truck circular knitting machine (M/C).

Objects:

1. To know about the difference between single jersey single truck and single jersey four truck circular knitting machine.
2. To know about modern development of single jersey four truck knitting machine.
3. To know about the problematic area of single jersey single truck knitting machine.
4. To identify the single truck & 4-truck circular knitting machine.

Introduction:
Circular knitting machine is a common machine in knitting industry. More than 70% of knitted fabric is produced in single jersey machine. In conventional machine there is only one cam truck. So we can produce only basic single jersey fabric in this machine. But in modern machine there is four truck in the cylinder. So we can produce maximum 4 (four) wales in a repeat. To produce more than 4 wales in a repeat we need jacquard mechanism.
